We're dividing 50912945 by 642 
The aim is to understand the frequency of 642 in 50912945.

Moving on to step 1:
642 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 642

Let's proceed to step 2:
642 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 642

On to step 3:
642 goes into 509 0 times with a remainder of 509.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 509 to get 509.
Include the next digit (1) from the dividend after 509, then repeat: 5091 / 642

Let's proceed to step 4:
642 can be fit into 5091 7 times, resulting in a remainder of 597.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4494 from 5091 leaves us with 597.
Grab the next digit (2) from the dividend, add it to 597, then carry on: 5972 / 642

Moving on to step 5:
642 goes into 5972 9 times with a remainder of 194.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtract 5778 from 5972 to get 194.
Append the next digit (9) from the dividend to 194 and continue with: 1949 / 642

Going ahead to step 6:
642 goes into 1949 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 793.0
If we subtract 1926 from 1949, we get 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 642

Step 7:
If we divide 234 by 642, we get 0 and a remainder of 234.
Use 0 as the next digit of our solution. 
Result so far: 7930.0
Subtracting 0 from 234 leaves us with 234.
Include the next digit (5) from the dividend after 234, then repeat: 2345 / 642

On to step 8:
642 can be fit into 2345 3 times, resulting in a remainder of 419.
The next digit of our result is 3. 
Result so far: 79303.0
Deduct 1926 from 2345 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Moving on to step 9:
The number 642 fits into 4190 6 times, leaving a remainder of 338.
The number 6 becomes the next digit in our result. 
Result so far: 79303.6
If we subtract 3852 from 4190, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 10:
If we divide 3380 by 642, we get 5 and a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 79303.65
If we subtract 3210 from 3380, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 11:
1700 divided by 642 is 2 with a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 79303.652
Subtract 1284 from 1700 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 12:
4160 divided by 642 is 6 with a remainder of 308.
The number 6 becomes the next digit in our result. 
Result so far: 79303.6526
If we subtract 3852 from 4160, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 13:
If we divide 3080 by 642, we get 4 and a remainder of 512.
Use 4 as the next digit of our solution. 
Result so far: 79303.65264
Subtract 2568 from 3080 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 14:
If we divide 5120 by 642, we get 7 and a remainder of 626.
The next digit of our result is 7. 
Result so far: 79303.652647
If we subtract 4494 from 5120, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 15:
642 can be fit into 6260 9 times, resulting in a remainder of 482.
The number 9 becomes the next digit in our result. 
Result so far: 79303.6526479
If we take 5778 away from 6260, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 16:
If we divide 4820 by 642, we get 7 and a remainder of 326.
The next digit of our result is 7. 
Result so far: 79303.65264797
Deduct 4494 from 4820 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

In conclusion, the division gives 79303.65264797 with a balance of 3.26e-07.
